To 6:32 Mama may concern." V I Be it knownthat I, MICHAEL 'HALLANAN, a, States, residin at New York city, in the county ofNew fork and 5 State of New York, have invented certain 7 new and-useful Improvements in' N onskid citizen of the United Devices for Tires,.of which the following is a specification.

y invention relates to non-skid traction devices for tires and it is myobjectto produce a devicewhich can be easily applied to and removed from tires, especiallyr of the pneumatic type, which will fittires and rims of difierent sizes and which will be rigidly held in place on the tire. v a In the drawing Fig. 1 is an end view of my device, partly in section; Fi'g. 2 a side view of the structure of Fig. l, partly in section; and Fig. 3 a top viewof tion plate.

I Q i In use the bolt 8 is removed and the sleeves, turn-buckles and clamp plates swung out so that the platel can be laid on the face of the tire. The clampplates are then swung into contact'wi'th the felloe and the bolt 8 inserted and tightenedup-to'lock the clamp plates to the felloe which is;

gripped between the elastic packing- The turn buckles are then tightened up todraw the plate 1 into solid contact with the tire tread whereupon the to the tire and wheel,
